TELESCOPIC MOUNTING FOR GUNS.

SPECIFICATION" forming part of Letters Patent No. 681,202, dated August27, 1901.

Application filed December 15, 1900. Serial No. 40,044. (No model.)

To aZZ whom it may concern..-

Beit known that I, HENRYL. DE ZENG., J12, a citizen of the UnitedStates, residing at Buffalo, in the county of Erie and State of NewYork, have invented new and useful Improvements in Telescope-Mountingsfor Guns, of which the following is a specification.

The object of this invention is to produce an improvedtelescope-mounting for guns which permits of readily and accuratelyadjusting the telescope on the gun and which is not liable to get out oforder by striking obstacles or to be loosened by the firing shocks ofthe gun.

In the accompanying drawings, Figure 1 is a fragmentary side elevationof a gun provided with my improved telescope mountings. Fig. 2 is afragmentary top plan View on an enlarged scale,showing the frontmounting connecting the telescope and the gun, the relative position ofthe gun and telescope being exaggerated to illustrate the invention moreclearly. Figs. 3, 4, and 5 are transverse sections, on an enlargedscale, in lines A A, B B, and O C, Fig. 1, respectively. Fig. 6 is afragmentary longitudinal section in line D D, Fig. 3. Fig. 7 is afragmentary longitudinal section, on an enlarged scale, in line E E,Fig. 1.

Like numerals of reference refer to like parts in the several figures.

The gun l and the telescope 2, which is mounted lengthwise upon the gun,may both be of any suitable construction, and the mountings which adjustably support the telescope on the gun may be constructed to supportthe telescope lengthwise over the gun or on one side thereof. Themountings which are shown in the drawings are constructed to support thetelescope on the left-hand side of the gun.

The telescope is adjustably connected at its front end with the gun by amounting which permits the telescope to be tilted fore and aft and to beshifted bodily laterally with reference to the gun-barrel, and the rearend of the telescope is adj ustably connected with the gun by a mountingwhich permits the telescope to be tilted fore and aft and also turn in ahorizontal plane on a Vertical pivot.

The rear mounting, which adjustably connects the rear end of thetelescope with the gun, is substantially the same as that shown anddescribed in my pending application for Letters Patent fortelescope-mountings for guns filed May 28, 1900, Serial No. 18,182, andis constructed as follows:

3 represents a split clamping-collar which embraces the rear part of thetelescope and which is clamped to the same by a screw 4, connecting theends of the split collar. The lower side of the clamping-ring isprovided with a depending tubularadjusting-shank 5, having an internalscrew-thread. The lower end of the shank slides in a verticalguidesleeve 6, which is arranged on a supportingplate '7, mounted on theleft side of the gunframe.

8 represents a vertical adjusting screw whereby the adjusting-shank andthe parts connected therewith are raised and lowered. This screw isarranged lengthwise in the guide-sleeve 6 and engages with its upperscrew-threaded end in the internal thread of the adjusting-shank, whileits lower end is connected with the lower. end of the guidesleeve, sothat it is free to turn, but is held against axial movement. Therotatable connection between the screw and guide-sleeve consists of ahead 9, arranged on the lower end of the screw and provided with adownwardly-facing shoulder 10, a retaining-cap 11, secured to the lowerend of the guide-sleeve by a screw-joint and provided with aninwardly-projecting flange or shoulder 12, hearing against the shoulderof the head, a fingerpiece or button 13, arranged on the lower end ofthe head and bearing against the under side of the retaining-cap, and afasteningscrew 14, connecting the finger-piece and the head of theadjusting-screw. Upon turning the adj Listing-screw 8 by means of itsfinger piece the adjusting-shank and the rear part of the telescopemounted on the upper end thereof are raised or lowered, and therebytilted fore and aft more or less relatively to the gun-barrel. In orderto permit the sup porting-plate? and the parts mounted thereon to followthe movement of the adjusting shank as the latter tilts while beingraised 100 and lowered, one end of the supporting-plate is pivoted by ahorizontal or transverse screw 15 to the side of the gun-frame. Thesupporting-plate is held in position after adjustment by aclamping-screw 16, arranged in a segmental slot 1'7 in the opposite endof the supporting-plate. The elevation of the rear part of the telescopewith reference to the gun-barrel is determined by graduations 18,arranged on the outer side of the adjustingshank and adapted to be readoff at the upper end of the guide-sleeve. Partial turns of theadjusting-screw are indicated by grad uations 19, arranged on theperiphery of the finger-piece and moving past a mark 20 on theretaining-cap, as'shown in Fig. 1.

The front mounting, whereby the front end of the telescope is adjustablysupported on the gun, is constructed as follows:

21 represents a bracket which is secured to the top of the gun-barreland which is provided with a laterally-projecting tubular shank 22. Thebracket is fastened to the gun-barrel by a dovetail joint 23 and aclamping-screw 2%, arranged on the bracket and bearing against thegunbarrel, as shown in Figs. 4 and 6.

25 represents a tubular carriage or sleeve which is capable of slidinglengthwise on the tubular shank of the bracket and also capable ofturning on said shank.

2o represents a supporting-collar which receives the front end of thetelescope and which is pivotally connected on its underside by avertical pivot with the top of the carthe carriage is moved lengthwiseon the shank of the bracket. This screw engages at its inner end with aninternal screw-thread in the supporting-shank 22, while its outer end isconnected with the carriage 25, so that it is free to turn within thecarriage, but the latter is compelled to move axially with the screw.The rotatable connection between the screw 28 and the carriage 25consists of a head 29, arranged on the outer end of the screw and havingan outwardly-facing shoulder 30, which engages with an inwardly-facingshoulder 31 on the carriage, a rotary finger-piece 32, mounted on theouter end of the carriage, and a fastening-screw 33, conmeeting thefinger-piece and the head of the adjusting-screw, as shown in Figs. 1and 4.

The lateral position of the front end of the telescope relative to thefront end of the gunbarrel is determined by graduations 34, which arearranged on the supporting-shank and which are read off at the inner endof the carriage-sleeve and denote complete turns of the adjusting-screw28. Partial turns of the adjusting-screw are indicated by graduations35, arranged on the periphery of the fingerpiece 32 and moving past amark 36 on the carriage-sleeve, as shown in Fig. 3.

Upon adjusting the telescope the same is first moved forward orbackwardly in its front and rear supporting-collars to the desiredposition. The front part of the telescope is then moved bodily laterallytoward or from the barrel of the gun by adjusting the front mountinghorizontally, and then the rear part of the telescope is moved bodily upor down with reference to the gun-barrel by adjusting the rear mountinguntil the telescope and gun-barrel are in the desired relation, afterwhich the clamping-screws at 16 are tightened. Upon moving the frontpart of the telescope toward or from the gun-barrel the front part ofthe telescope turns in a substantially horizontal plane on the verticalpivot 27, which connects the supporting-collar 26 and thecarriage-sleeve 25 of the front mounting, and the rear part of thetelescope turns in a substantially horizontal plane on the verticalpivot 5 6, connecting the supporting-collarand the supporting-plate ofthe rear mounting. Upon adjusting the rear part of the telescope up ordown the rear supporting-plate 7 turns in a vertical plane on thehorizontal pivot 15, which connects the supporting-plate and thegun-frame, and the front part of the telescope turns in a vertical planeby reason of the horizontal pivotal connection between thecarriage-sleeve 25 and the shank 22. When the wind-pressure is towardthe right side of the gun, the front end of the telescope and the barrelare separated, as shown in full lines in Fig. 2, until the telescope andgun-barrel diverge forwardly sufficiently to compensate for thedeviation of the projectile which is produced by the action of the windor drift. When the windpressure is toward the left side of the gun, thefront end of the telescope and the gunbarrel are moved toward eachother, so that the telescope and barrel converge forwardly, as shown bydotted lines 1 in Fig. 2, and the wind-pressure toward that side of thegun is overcome.

By this construction of telescopemountings for guns the position of thetelescope maybe readily and accurately adjusted to any required anglerelative to the gun-barrel for sighting at ranges of varying distancesand also to compensate for wind in either direction.

The forwardly-diverging position of the gun and telescope, as shown infull lines, Fig. 2, and the forwardly-converging position of these partsshown in dotted lines in the same figure are both exaggerated for thepurpose of more clearly illustrating the lateral adjustment of the gunand telescope with reference to each other.
